The calculator counts calendar days between two dates. It handles months of 28, 29, 30 and 31 days, including 29 February when it falls in the range.
A hotel stay from 10 June to 14 June is 4 nights. A leave application covering 10 June through 14 June spans 5 dates. For that second count, select Count both dates.
Dates are counted without times of day, so your time zone does not change the result.
Pick both dates and select Calculate. To type a date instead of using the calendar, select Type manually and use DD-MM-YYYY. The signed difference is negative when the end date is before the start date.
Count the days after the start date through the end of its month. Add the days in the intervening full months, then add the day number of the end date.
| Part of the date range | Days |
|---|---|
| 16 to 31 August | 16 |
| September through December (30 + 31 + 30 + 31) | 122 |
| 1 to 26 January | 26 |

The calculator subtracts the calendar day numbers, which account for month lengths and leap years.
A Gregorian year is a leap year if it is divisible by 4, except that century years must also be divisible by 400. That makes 2028 and 2000 leap years, while 2100 is a common year.
By default it counts the elapsed days. 1 May to 6 May is 5 days. Select Count both dates to include the start and end dates and get 6 days.
The absolute gap and the weeks-and-days breakdown stay the same. The signed difference changes sign, so 6 May to 1 May gives −5 days.
Yes. 28 February to 1 March is 2 days in a leap year and 1 day in a common year.
Yes. The result counts every calendar day, including Saturdays, Sundays and holidays.
A common year has 365 days and a leap year has 366. The extra day is 29 February.
The result is shown in days and weeks. Calendar months vary from 28 to 31 days, so a fixed number of days does not always represent the same number of months. For a rough estimate, a Gregorian month averages about 30.44 days.
No. The calculator uses calendar dates without times of day, so the same pair of dates gives the same result in every time zone.
Calculations use the Gregorian calendar and its leap-year rules. Last updated .
